EMBODIMENT OF THE INVENTION Hereinafter, the marking device 1 based on each embodiment of this invention is demonstrated with reference to drawings. FIG. 1 shows a diagram illustrating a marking device 1 according to a first embodiment and a marking operation using the same. The marking device 1 is used to mark a location where a fastener 4 such as a nail or a screw (see FIG. 2) is to be driven into a building material 2 such as plywood, and includes a long member 6 and a marking tool 8. The elongated member 6 is placed on the building material 2, and a plurality of marking holes 12 are bored at a predetermined interval D on a straight line 10 formed in the longitudinal direction of the elongated member 6.

The elongated member 6 has a long plate shape as shown in FIG. 1, for example, and can be made of various materials such as wood, plastic, and metal, and may or may not be flexible. It's fine without it. The flexible elongated member 6 can be stored compactly by being rolled up or folded in the longitudinal direction when not in use. Further, a bent portion (not shown) may be formed on the elongated member 6 to facilitate folding.

The locations at which the fasteners 4 are driven into the building material 2 are often predetermined at predetermined intervals depending on the type of the building material 2 and the specifications of the building in which the building material is used. Therefore, the interval D between each marking hole 12 is set to a predetermined distance, such as 75 mm, 100 mm, 150 mm, or 200 mm, where the stopper 4 is to be driven.

The marking tool 8 is used to mark the building material 2 through each marking hole 12 by rubbing it against the elongated member 6 while moving it along the straight line 10. The marking tool 8 is, for example, chalk, and in this case, when the chalk is rubbed against the elongated member 6 along the straight line 10, the building material 2 is marked by the chalk powder that falls from each marking hole 12. will be held. Chalk is suitable because it can be easily cleaned even if it adheres to the elongated member 6.

Further, at least one of the marking holes 12, preferably formed near one end of the elongated member 6, is used to drive a temporary fastener 14 such as a nail into the elongated member 6 to temporarily fasten the elongated member 6 to the building material 2. It may also be used as a hole 16 for temporary fixing. Thereby, movement and rattling of the elongated member 6 during marking work can be suppressed, and the working efficiency of marking work can be improved. Note that the temporary fastener 14 is removed after the marking work.

FIG. 2 shows the elongated member 6 according to a modification of FIG. 1 as a partial perspective view. The elongated member 6 may have a grooved line 18 having a predetermined width W in a region including the straight line 10 along its longitudinal direction. Thereby, the marking tool 8 can be moved without deviating from the straight line 10, so that it is possible to reliably mark a desired location on the building material 2 through each marking hole 12. Therefore, the efficiency of marking work can be further improved. Note that the grooved line 18 is not limited to the keyway shape shown in FIG. 2, but may be a downwardly convex curved shape.

FIG. 3 is a diagram illustrating the driving operation of the stopper 4. After removing the elongated member 6 from the building material 2, a tool such as a power tool 22 is used to drive the stopper 4 into each marking location 20 formed in the building material 2 through each marking hole 12 by marking work. Thereby, the fasteners 4 can be easily driven into the building material 2 in a straight line with the interval D between them.

As described above, when marking work is performed using the marking device 1 of this embodiment, the marking procedure is performed by moving the set of the marking device 1 and the marking tool 8 along the straight line 10, and the marking work is performed in two steps. It's over. In addition, each marking hole 12 is pre-drilled in the elongated member 6, and the building material 2 can be quickly marked by a simple operation of rubbing the marking tool 8 against the elongated member 6 along the straight line 10.

Thereby, it is not necessary to perform the work carefully in order to avoid marking the wrong place, so the work efficiency related to the marking work can be greatly improved. Furthermore, the marking device 1 is composed of a long member 6 and a marking tool 8, and does not require a conventional marking section for setting a marking location or a conventional holder for holding a marking tool. Thereby, the production cost of the marking device 1 can be significantly reduced. Therefore, it is possible to provide a marking device 1 that has a simple structure, is easy to use at a construction site, and has improved marking work efficiency.

FIG. 4 shows a diagram illustrating a marking device 1 according to a second embodiment and a marking operation using the same. In the case of this embodiment, the elongated member 6 is a scale tape 26 of a tape measure 24, and a dimensional scale is formed in advance on the scale tape 26. The marking holes 12 are formed at intervals D on the straight line 10 formed in the longitudinal direction of the scale tape 26.

Further, a stopper 28 is attached to one end of the scale tape 26 in the longitudinal direction. By locking the stopper 28 to one end of the building material 2, movement and rattling of the scale tape 26 during marking work can be suppressed, and the work efficiency of the marking work can be improved.

FIG. 5 shows a longitudinal cross-sectional view of the scale tape 26. The scale tape 26 is made of metal and has a downwardly convex curved shape in the width direction so that it can be easily extended in a straight line when pulled out from the measuring tape 24 . Thereby, the marking tool 8 can be moved without deviating from the straight line 10, so that it is possible to reliably mark a desired location on the building material 2 through each marking hole 12. Therefore, the efficiency of marking work can be further improved.

As described above, in the case of the present embodiment, as in the case of the first embodiment, a marking device 1 is provided which has a simple structure, is easy to use at a construction site, and further improves the work efficiency of marking work. can do. Particularly in the case of this embodiment, since the tape measure 24 used for dimension measurement can also be used as the marking device 1, the burden on the worker is reduced and the burden on the worker can be reduced. Further, it is suitable because the dimension of the interval D can be confirmed during marking work.

This concludes the description of each embodiment of the present invention, but the present invention is not limited to the above-described embodiments, and various changes can be made without departing from the spirit of the present invention. For example, the interval D between each marking hole 12 is not limited to the above-mentioned dimensions, and various dimensions can be set, and the interval D does not necessarily have to be equal, and intervals D of a plurality of dimensions may coexist. It's okay. Further, the elongated member 6 of the first embodiment may also have a dimensional scale formed in advance like the scale tape 26 of the second embodiment.

The marking tool 8 can also be used with various pens other than chalk, for example, as long as it is possible to mark the building material 2 through each marking hole 12 by rubbing the elongated member 6 against it while moving it along the straight line 10. It is also possible to use ink or India ink. However, it is preferable that the marking agent used in the marking tool 8 is a hardened powder material, so that it can easily drip down into each marking hole 12 and make markings, and it is also easy to clean after use. .
